In one embodiment, dispersants are injected directly into a plume of oil in a subsea environment. The dispersant is supplied from a vessel, through a tubular string and flows through a routing manifold into a flexible hose. The hose then transports the dispersant to a distribution manifold, which is disposed on the sea floor, and permits injection of dispersants at multiple locations at the same time around the leaking oil. Injection of dispersants from the distribution manifold may be through injection wands, or the dispersant may be transferred to a containment or collection device located above the plume of oil, wherein nozzles are disposed around the circumference of such containment or collection device. If the dispersants are injected into the leaking oil through injection wands, such wands may be held and / or manipulated by an ROV.

The invention relates to an oil dispersant underwater injection effect assessment method, and belongs to the technical field of marine environment simulation test. The oil dispersant underwater injection effect assessment method comprises the following steps: 1, experiment crude oil is injected to water from the bottom of an underwater overflow oil simulation test apparatus; 2, an oil dispersant is injected in a direction vertical to the injection direction of the crude oil, and is mixed with the crude oil; 3, information of oil drops dispersed by the oil dispersant in the water is acquired through adopting an industrial camera with a microlens; and 4, the change of the particle size of the oil drops is analyzed to evaluate the use effect of the oil dispersant. The method has the advantages of convenience in operation, fastness, high efficiency, accurate assessment of the underwater injection effect of the oil dispersant, direct and effective result, and wide application range.

The invention discloses a method of hazard-free treatment and resource recovery of oil silt, and adopts a physical and chemical combinative method to carry out comprehensive treatment of the oil silt. Composite effective oil dispersant is first adopted to conduct high-efficiency separation of oil, mud and sand with the crude oil extraction rate of the oil silt or the oil sand being above 99.99 percent; vacuum absorption is then employed to separate water bodies from the silt and the removal rate of harmful substances in the oil silt or the oil sand reaches above 99.99 percent; the harmful substances in water are next removed by the technique combining compound filtering and precision filtering. The oil contained in the silt after treatment is less than 600 mg / kg, which meets the corresponding national emission standard; the silt after the hazard-free treatment can be applied to roadbed construction or well field paving; the quality of water after treatment can achieve the national wastewater discharge standard of grade I and be reused in the treatment; the oil silt or the oil sand after being treated by the treatment method can achieve the hazard-free treatment and a great deal of crude oil can be recovered.

The invention relates to the technical field of regeneration field mixed asphalt and particularly relates to regeneration field mixed asphalt and a preparation method thereof. The regeneration field mixed asphalt is prepared from the following raw materials in percentage: 15-55% of waste asphalt pavement material, 45-85% of new aggregate, asphalt-aggregate ratio being 4-8%, limestone ore powder being 4-8% of new aggregate, dehydrated crude oil being 5-20% relative to the total weight of new and asphalt materials, catalytic cracking oil slurry being 5-10% relative to the total weight of new and asphalt materials, and a lubricating oil dispersant being 1-12% relative to the total weight of new and asphalt materials. According to the invention, a waste asphalt pavement is dug up and taken back to a mixing factory to be crushed all together; proportioning design is carried out according to quality requirements of pavements at different grades so as to determine the addition proportion of waste asphalt mixture so that the waste asphalt mixture is re-blended according to a certain proportion in a mixer to generate a new mixture, thus obtaining excellent regenerated asphalt concrete which can be used for paving a regenerated asphalt pavement. By implementing the preparation method of the regeneration field mixed asphalt, regeneration and recycling of resources can be realized and the road material cost is reduced.
